Filed: 1999-08-17
Abstract: A priority access channel assignment system and a messaging protocol for wireless mobile stations. A mobile station (MS1, ..., MS10) originates a call that manually or automatically includes a request for priority access. If system resources are unavailable to process the call immediately, the origination message is processed by a base station (BS1, BS2) and a mobile switching center (MSC) using a plurality of messaging protocols to determine the time at which the call was originated and the priority associated with the call. Based on priority and arrival time, the base station (BS1, BS2) queues the call where higher priority calls are placed in a higher position in the queue than lower priority calls. Calls having identical priority may be placed in the queue in order of the time of arrival. When system resources become available, the pending call with the highest priority is assigned a channel and the call is processed in a conventional manner.

Title: Fluid pressure actuated blood pumping systems and methods with continuous inflow and pulsatile outflow conditions
Inventor: VISHNOI ROHIT
IPC: A61M37/00
Filed: 2000-08-29
Abstract: Blood processing systems (10) and related methods place first (PP1) and second (PP2) fluid actuated pump stations in in-line communication between a source and a destination. The systems and methods apply fluid pressure pump strokes to the first and second pump stations to convey fluid from the source to the destination. The systems and methods switch between a first flow mode and a second flow mode. The first flow draws a fluid volume into the first pump station from the source and expel a fluid volume from the second pump station to the destination. In the second flow mode, the pump strokes draw a fluid volume into the second pump station from the source and expel a fluid volume from the first pump station to the destination. The pump strokes are synchronized so that flow from the source is essentially continuous while fluid flow to the destination is pulsatile.
